Introduction to MARPOL Annex VI Amendments
On June 17, 2021, during the 76th session of the International Maritime Organization‘s Marine Environment Protection Committee (MEPC 76), significant amendments to MARPOL Annex VI were adopted. These amendments introduce new regulations aimed at enhancing the energy efficiency of existing ships and reducing greenhouse gas emissions from international shipping. Specifically, the amendments include the introduction of the Energy Efficiency Existing Ship Index (EEXI) and the Carbon Intensity Indicator (CII), which are set to enter into force on November 1, 2022. This article provides a comprehensive overview of these regulations, their implications for the maritime industry, and guidance on compliance.
Amendments to the International Convention for the Prevention of Pollution from Ships (MARPOL) Annex VI entered into force on 1 November 2022. Developed under the framework of the Initial IMO Strategy on Reduction of GHG Emissions from Ships agreed in 2018, these technical and operational amendments require ships to improve their energy efficiency in the short term and thereby reduce their greenhouse gas emissions. From 1 January 2023 it became mandatory for all ships to calculate their attained Energy Efficiency Existing Ship Index (EEXI) to measure their energy efficiency and to initiate the collection of data for the reporting of their annual operational carbon intensity indicator (CII) and CII rating.
Overview of Key Regulations:
Energy Efficiency Existing Ship Index (EEXI)
The EEXI is a technical measure designed to assess and improve the carbon design efficiency of existing vessels. It applies to most in-service ships over 400 Gross Tonnes (GT) engaged in international operations. The EEXI aims to ensure that these vessels meet specific energy efficiency standards, which are aligned with the International Maritime Organization’s (IMO) strategy to reduce greenhouse gas emissions from shipping.
Key Features of EEXI:
- Applicability: The EEXI applies to existing vessels over 400 GT.
- Compliance Deadline: Ships must demonstrate compliance with EEXI requirements during their first annual, intermediate, or renewal International Air Pollution Prevention (IAPP) survey after January 1, 2023.
- Technical Measures: The index assesses various technical factors that influence a ship’s energy efficiency, including engine power and design characteristics.
–
Carbon Intensity Indicator (CII)
The CII serves as an operational efficiency metric that evaluates a vessel’s carbon intensity over time. It is crucial for monitoring and reporting the carbon emissions generated during a ship’s operations.
Key Features of CII:
- Operational Measurement: The CII provides a continuous assessment of a ship’s carbon intensity based on its operational data.
- Rating System: Ships will receive a CII rating that reflects their performance in reducing carbon emissions.
- Implementation Timeline: The CII will be implemented starting January 1, 2023, with ongoing assessments thereafter.
Implications for Shipping Stakeholders
The adoption of EEXI and CII regulations presents both challenges and opportunities for various stakeholders within the maritime industry:
–
Shipowners and Operators
- Compliance Requirements: Shipowners must ensure that their fleets comply with EEXI and CII regulations by developing strategies for retrofitting or modifying vessels as necessary.
- Operational Adjustments: Operators will need to adjust operational practices to improve carbon intensity ratings and meet performance benchmarks.
Technical Superintendents and Ship Managers
- Implementation Planning: Technical superintendents are tasked with developing timelines for compliance and ensuring that all necessary modifications are executed efficiently.
- Training and Awareness: There is a need for training staff on new operational practices related to energy efficiency and carbon intensity monitoring.
Flag State Surveyors
- Regulatory Oversight: Flag state surveyors will play a critical role in verifying compliance with EEXI and CII requirements during inspections.
- Documentation Review: Surveyors must be familiar with the documentation required for demonstrating compliance.
Consultants and Ship Designers/Builders
- Advisory Role: Consultants will be essential in advising shipowners on compliance strategies, including potential retrofitting solutions.
- Design Innovations: Ship designers may need to innovate new designs that inherently comply with EEXI standards for future vessels.

Relationship Between EEDI, EEXI, and SEEMP
Understanding the relationship between various efficiency indices is crucial for effective compliance:
- Energy Efficiency Design Index (EEDI): This index applies to new ships, setting mandatory energy efficiency standards based on design. In contrast, EEXI focuses on existing vessels.
- Ship Energy Efficiency Management Plan (SEEMP): The SEEMP is enhanced under the new regulations to ensure ongoing operational improvements in energy efficiency. It serves as a management tool that outlines how a vessel will achieve its energy efficiency goals.
Future Implications
The amendments to MARPOL Annex VI signal a significant shift towards greater accountability in reducing greenhouse gas emissions from shipping. As these regulations take effect, it is expected that:
- Increased Scrutiny: Regulatory bodies will increase scrutiny on compliance efforts, leading to potential penalties for non-compliance.
- Market Competitiveness: Vessels that successfully comply with EEXI and CII standards may gain competitive advantages in markets increasingly focused on sustainability.
- Technological Advancements: There will likely be an acceleration in technological advancements aimed at improving vessel efficiency and reducing emissions.
The adoption of the EEXI and CII regulations under MARPOL Annex VI represents a critical step towards achieving sustainability goals within the maritime industry. Stakeholders must proactively develop compliance strategies to navigate this evolving regulatory landscape effectively. By understanding these new requirements and their implications, shipowners, operators, and other maritime professionals can position themselves for success in an increasingly environmentally conscious market. Upon successful completion of relevant training courses focused on these amendments, participants will receive certification recognizing their competence in implementing these essential regulations.
